Finely textured foliage has a feathery, fern-like appearance and foul odor when crushed. Stems are reddish in color and woody at the base. Mature plants are narrow and columnar, growing to 6 ft tall. Tiny, barely detectible flowers produced on numerous small flowerheads. Grows from seed and spreads underground from roots that grow laterally from the main taproot. If not removed completely, plants will re-sprout from broken stems. Found throughout the southeastern United States from MA to TX.
